More to come. The JKS Bar-Pin Eliminators (BPEs) are a great solution to the weak link "dog-bone" bar pin found in the XJ shocks. The front shocks have a post on top and barpins on the lower attachment, while the rear shocks use a bar pin on top and a conventional mounting stud on the bottom end. The problem with the barpin is that the small mounting bolts can loosen or break, breaking the barpin.
